The worst usability loss is showing multiple events on a day in calendar view. I like to see a calendar view to get an overview but now most of my events have been replaced with a useless '2+ more' or '3+ more'. The real sore point is that the '2+ more' takes up exactly 2 lines of space so they had just enough space to show me my 2 appointments but have decided I'd be much more interested to see this useless '2+ more' link. Outrageous!
